When I wanted to do a clean installation of SL7.1 on my laptop, I experienced a strange problem.During installation, the wireless controller was recognised and I could configure it (including autoconnect).After the minimal installation, there was no network (where it was when i did a clean SL7.0 installation).

That would be strange. I did the installation including WIFI configuration twice to rule out "human error". All I know is that after both tries, I installed MATE by hooking up a cable and manually activating the wired network. Even after I got the desktop and all tools, there was nothing related to the wifi
